We inlaid this ring with Black Jade and drilled it
for a Diamond tube and Masonic emblem
A jeweler in Michigan had a customer who wanted a ring custom designed and set with a black inlay, a Diamond, and a Masonic emblem.
The jeweler had some ideas on how he wanted to construct the ring with a hole countersunk in the back of the Black Jade to hide the head of the screw. I have described that below.
